Specification forming part of Letters Patent No. 94,175, dated August 31, 1869.

Be it known that I, JOHN BLAGKIE, nowof 1 the city, county, and State of New York, have invented a new and useful Improvement in Printing-Telegraphs; and I dohereby declare that the following is a full clear, and exact description of the construct on and, operation of the same, reference being bad to the an nnexed drawings, making a part of this, specification, in which the same letters refer to the same parts in-each figure. I I Figure 1 is a perspective view of one side, andFig. 2 is a perspective view of the opposite side, having, however, only those parts represented which could not be exhibited in Fig, 1, from their position. 4

a cog-wheel, providedwith pins a rat regular intervals, whose office A; Sp a spring for op-' the striker St when relieved from the to bring the ball or buffer b is to depress the striker St and its arm A crating pins w a, so as suddenly against the particular type to be printed from, and yet allow the buffer b to rebound therefrom and remain free.

The operation of my invention," and so much of ,its construction as is not given above, may be described magnet M draws. the armature A to v itself, overcoming hook of the escapement E on the corresponding tooth of the escapement-wheel e.

The lefthand esc'apement-hook being freed, the right-hand one drops into its notch, giving the left-hand spring: Sp opportunity to act,

through the cog-wheels w and w and the pinions on the arbor of the ratchet-wheel R,

upon the ratchet-wheel R in such a way as "to lift the clutch G outof the ratchet in whichit. happens to he by a sliding motion, and drop it into the next ratchetto the left. 'Inp'roducing this effect, a, Z, and 0 being firmly fixed on the nave or arborn, the spring Sp is'overcome, the lever I pressed back, the

-.arm a lifted by sliding on the lever I, also the arms 02" andd, the small spring Sp being overcome. By this means the stop-arms a" and a" are freed from each other, which, when they engage each" other, prevent any motion in the right-hand system of wheels, &c.,-- or thestriking mechanism.

The stop-arm; a, being freedfronl the stoparm a, and being actuated bytlie right-hand spring Sp and its, system, commences to re volve about'its-shaft. But simultaneously with the lifting of the stop-arm a", and the consequent freeing of the stop-arm' th as follows, viz: The circuit a being completed in the usual manner, the

p the small spring S and the frictionof the left-hand 2 cares segment S has been also lifted by its arm a to such an extent that the stop-arm a is engaged by it when it has described about onehalf of its circular sweep, and held. Thus only slight action of the printing-spring Sp and its system has been permitted, and preparation only allowed. Meanwhile the constant tendency of the spring Sp" is to pull the lever l to itself, audconsequentlyto depress the arm a, and so free thestop-arm a!" from thesegment on hook S. l This tendency is, however, resisted by the fly f, through its combination of machinery, for a time the spring 'Sp having to drive this fly against the air, and being modified in its action by this necessity..

I would here say that I contemplate the im- .mersion of the fly f, made of suitable size, in water or other fluid, wherein, revolving, as in this case, in the air, a similar regulating result will be secured. Supposing, now, that wheel were at zero, or rather presented zero to the printing-bob 6 before the circuit was completed, as above, and the. next character upon the wheel was that of letter A, and no break or repetition of the circuit has been made, as soon as the spring Sp" has had time to overcome the resistance of the fly f it will draw the angled lever Z to itself, the result of which will be the depression of the arm a and segment S far enough to clear or disengage the stop-arm a' therefrom, while 'the clutch or pawl O is dropped into the next ratchet of the ratchet-wheel R. Simultaneously with the freeing of the stop-arms a! and a! the arm 11''" has been lifted so as to clear its hooked end from the notch of thecam c. This is the result of the motion permitted in the stoparm a from the stop of the stop arm a to Y the hold of the segment S, the hooked end of the arm a'' being placed, as it were,,on the back of the cam '0, andnot to be againtaken into its one notch until the wheel w", to which the cam c issecured, either directly or by its arbor, has nearly completed one revolution.

The ratchets of the ratchet-wheel R corresponding in'number to the number of letters or other characters on the letter-wheel, the

I movement of the-ratchet-wheel described has permitted the letter-wheel L to move one stage or letter, and then remain stationary, waiting events.

The wheel -u7 w to, being free to move,

as described, when the. spring Sp" has completed its work, proceed in their motion ,whereby the next succeeding pin-X of the wheel to is pressed upon the rounded corner of the striking -lever St sliding thereon, and depressing said striker until it reaches a certain point, when it is suddenly freed; Thereupon a spring, Sp', (in-the drawing represented as secured to the middle bar of the frame, as

shown in the drawing, .Fig. 1, and as indi-. cated by dotted lines,) passing on till, it reaches ;a.point-of'contact with a cam, m, securedon -the striker-shaft near itsbearing 0;", takes.

the letter, or type this striker in charge, and, it having been de-' pressed, as above, sudden reaction is given by this spring, whereby the bob b is brought in contact with the under side of the paper strip passing between it and the letter-wheel,

pressing the same suddenly and concussively against the type or character A, which be-. comes printed on said strip, the type being constantly inked by the ink-roller 1, against which the letter-wheel rotates; thus be accomplished while the carriers 0 0 and the paper strip. are in motion, for the re-[ bound of the bob 1) is instantaneous; and,further, thenext pin :19 engages the striker, and begins to prepare it for a repetition of 'the blow. If, however, it be desired to print the letter 0' instead. of A, or the third letter in v the alphabet, three completions and breaks to- 'gether must be made, as the teeth on the escapement'wheel e are just half in number of the characters on the type or letter wheel,

whereby the letter 0 will be presented and printed.

I now come to the description of the method whereby false printing is prevented while passing the. intermediate letters. As I have stated, the fly f gives time, during which the stop-arm a engages the segment S, while the arm a'' and cam 0 relieve the angled lever l from the pressure of thearm a. If, now, the

circuit. first above completed be broken, the armature A will be relieved, its spring S will act, the right-hand tooth or hook of the es 'capement E will be freed, and the left-hand one will drop into the next notch, the clutch C will strike; on the point 'of the next ratchet only in passing the segment S,'not freeing the stop-arm a', and consequently all' action of the striking or printing system being'pre vented still. The break and completion of the'circuit must, however, be done with proper rythmic relation to the strength of springs or forces used in the printing-machine, and must be continuous, and any number of letters may thus be passed without their being printed, Each break and completion of the circuit will drive the segment S up so as to perfect its hold on the stop-arm a. Meantime the fly f'iis rapidly revolving and steadying the action ofthe parts; but when the wheel to has nearly completed its revolution, the hook end 7 of the arm a/. dropping into the notch of the cam c, as it may do, because the clutch 0 has dropped into a ratchet, the long lever lhas followed it, and so relieved the arm -a-, the l step-arm a again drops far enough to engage the stop-arm a1, and preventffurther ac; tion of the machinery controlled thereby.

. While the stop-arm a" maybe used, asdescribed, to perform this stop function, iti'snot T V absolutely essential to the perfect working of the machine. For, omitting it altogether, the arm a" and cam a may be used to efl'ect the same'result by. simply making the cam a hookformed, instead of having an incline, as. in the dravgin np which the bent end of the arm a'i" easily s ides.

Printing may- The same mechanism which lifts a" lifts a',

and at the same time; hence I do not confine myself to the use of .the stop a". So, also, may the fly f be otherwise connected with andop erate upon the arm a, assay directly, Without the use of the long arm Z, and' even with the clutch 0. So might the arm aAbe made to perform its function, perhaps, if rested on the arm a, orthe clutch C.

These and; other possibilities of this sort I contemplate, and some of themhave I employed ian tliie course of experimental'construction inee i i .A co-ordi'nate function of the wheel 10, or its shaft or arbor, is to operate the carrier wheelso'o, whereby the printing-strip is carried along far enough to secure the requisite succession and spacing of the letters printed thereon. y

The zero-stop o is for regulating the letterwheel or disk, By pressing the thumb on the thumb-piece, the disk will revolve until engaged by'the pin it, when the disk will present zero to the printing-roller or bob.

This 'p rinting-telegraph may be operated by one wire at long distances and with very small battery-power. v

A. convenient instrument for-controlling and regulating he break and completion of circuit is v the; ordinary'dial, with characters on its face corresponding to those on the die or type-wheel, a movable pointer, with" knob for thumb and finger, together with the suitable? and usual means for breaking and completing circuit at the characters in succession. 1

What I claim as my invention, and desire to secure by Letters Patent, is-

, l. The segmental-formed detent S upon the arm a, operating in the manner and for the purpose as set 'forth.

2. The stop-arm a upon the arbor of the fly f, in combination with the segmental hook or detent S, as and for the purposesset forth.

3. The combination of the segmental-formed detent S, arm a, detaining-stop O, and fly f, operating substantially as set forth.

4. The combination of the arms a, and a, pivoted at the point n, and operating as and for the purposes described.

5. In combination with the printing-surface, the striking apparatus consisting of the lever St, arm A, and hammer b.-

6. In combination with the striking apparatus, the cam m, or its equivalent, and the spring Sp'', operating as and for the piu'poses set forth.

7. The stop-arm a, pivoted, at n, so asto act in the manner and for the purposes named.
